如何在android中读取Epub文件的所有内容？

我想阅读所有toc的所有内容。
你可以告诉我如何阅读内容表（toc）中的所有章节。
请发布修改后的代码，以便我们可以阅读所有内容或发布一些内容，以便我可以阅读内容。

public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); AssetManager assetsmanger=getAssets(); try { // find InputStream for book InputStream epubInputStream=assetsmanger.open("books/INCOME-TAX-ACT-1961.epub"); // Load Book from inputStream Book book = (new EpubReader()).readEpub(epubInputStream); // Log the book's authors Log.i("epublib", "author(s): " +book.getMetadata().getAuthors()); // Log the book's title Log.i("epublib", "title: " + book.getTitle()); String data=new String (book.getContents().get(3).getData()); String k=data; web1=(WebView)findViewById(R.id.webView1); // txt1=(TextView) findViewById(R.id.textView1); // txt1.setText(k); web1.loadData(k," text/html", "utf8"); Bitmap coverImage=BitmapFactory.decodeStream(book.getCoverImage().getInputStream()); Log.i("epublib" , "Coverimage is " + coverImage.getWidth() + " by " + coverImage.getHeight() + " pixels"); // Log the tale of contents logTableOfContents(book.getTableOfContents().getTocReferences(), 0); // list=(ExpandableListView)findViewById(R.id.expandableListView1); // img1=(ImageView)findViewById(R.id.imageView1); // img1.setImageBitmap(coverImage); } catch (IOException e) { // TODO Auto-generated catch block Log.e("epublib", e.getMessage()); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } private void logTableOfContents(List tocReferences, int depth) { // TODO Auto-generated method stub if(tocReferences== null ){ return; } for(TOCReference tocReference:tocReferences){ StringBuilder tocstring=new StringBuilder(); for(int i=0;i<depth;i++) { tocstring.append("\t"); } HashMap map = new HashMap(); String k= tocstring.append(tocReference.getTitle()).toString(); map.put("TOC",k); ArrayList<HashMap> list1 = new ArrayList<HashMap>(); list1.add(map); String t=k; Log.i("epublib", tocstring.toString()); logTableOfContents(tocReference.getChildren(), depth + 1); } } }

如果assets有必要的库和sampleepubfile.epub ，请使用此代码…

 import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.util.List; import nl.siegmann.epublib.domain.Book; import nl.siegmann.epublib.domain.TOCReference; import nl.siegmann.epublib.epub.EpubReader; import android.app.Activity; import android.content.res.AssetManager; import android.os.Bundle; import android.text.Html; import android.util.Log; import android.webkit.WebView; public class EPubDemo extends Activity { WebView webview; String line, line1 = "", finalstr = ""; int i = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); webview = (WebView) findViewById(R.id.webview); AssetManager assetManager = getAssets(); try { // find InputStream for book InputStream epubInputStream = assetManager .open("sampleepubfile.epub"); // Load Book from inputStream Book book = (new EpubReader()).readEpub(epubInputStream); // Log the book's authors Log.i("author", " : " + book.getMetadata().getAuthors()); // Log the book's title Log.i("title", " : " + book.getTitle()); /* Log the book's coverimage property */ // Bitmap coverImage = // BitmapFactory.decodeStream(book.getCoverImage() // .getInputStream()); // Log.i("epublib", "Coverimage is " + coverImage.getWidth() + // " by " // + coverImage.getHeight() + " pixels"); // Log the tale of contents logTableOfContents(book.getTableOfContents().getTocReferences(), 0); } catch (IOException e) { Log.e("epublib exception", e.getMessage()); } String javascrips = ""; try { // InputStream input = getResources().openRawResource(R.raw.lights); InputStream input = this.getAssets().open( "poe-fall-of-the-house-of-usher.epub"); int size; size = input.available(); byte[] buffer = new byte[size]; input.read(buffer); input.close(); // byte buffer into a string javascrips = new String(buffer); } catch (IOException e) { e.printStackTrace(); } // String html = readFile(is); webview.loadDataWithBaseURL("file:///android_asset/", javascrips, "application/epub+zip", "UTF-8", null); } @SuppressWarnings("unused") private void logTableOfContents(List tocReferences, int depth) { if (tocReferences == null) { return; } for (TOCReference tocReference : tocReferences) { StringBuilder tocString = new StringBuilder(); for (int i = 0; i < depth; i++) { tocString.append("\t"); } tocString.append(tocReference.getTitle()); Log.i("TOC", tocString.toString()); try { InputStream is = tocReference.getResource().getInputStream(); BufferedReader r = new BufferedReader(new InputStreamReader(is)); while ((line = r.readLine()) != null) { // line1 = Html.fromHtml(line).toString(); Log.v("line" + i, Html.fromHtml(line).toString()); // line1 = (tocString.append(Html.fromHtml(line).toString()+ // "\n")).toString(); line1 = line1.concat(Html.fromHtml(line).toString()); } finalstr = finalstr.concat("\n").concat(line1); // Log.v("Content " + i, finalstr); i++; } catch (IOException e) { } logTableOfContents(tocReference.getChildren(), depth + 1); } webview.loadDataWithBaseURL("", finalstr, "text/html", "UTF-8", ""); } }
